Central get manufacturer data in advertisement or scan response

[VM_TC]

Hi everyone,

I try to get manufacturer data with central device.

The peripheral device is normally correctly configured for both advertisement report and scan response :

I can't  get them in central in scan_evt_handler with filter matching : 

static void 
scan_evt_handler(scan_evt_t const *p_scan_evt)
{
    ret_code_t err_code;

    switch(p_scan_evt->scan_evt_id)
    {
        case NRF_BLE_SCAN_EVT_CONNECTING_ERROR:
        {
            err_code = p_scan_evt->params.connecting_err.err_code;
            APP_ERROR_CHECK(err_code);
        } break;

        case NRF_BLE_SCAN_EVT_FILTER_MATCH:
        {
            if(m_target_periph_name== config_get_device_name_str()) {

               ble_data_t read_data = p_scan_evt->params.filter_match.p_adv_report->data;
               uint8_t peripheral_serial_nb_ascii_data[60];

               for(uint8_t i =0 ; i<60 ; i++){
                  peripheral_serial_nb_ascii_data[i]=read_data.p_data[0+i];
                  NRF_LOG_INFO(" peripheral_serial_nb_ascii_data : %d",peripheral_serial_nb_ascii_data[i]) ; 
               }

Which method should I use?

Thanks,

Victor

Hi, 

To generate the NRF_BLE_SCAN_EVT_FILTER_MATCH event, the following types must match:
- one of the address filters,
- one of the name filters,
- one of the appearance filters,
- all of the UUID filters.

See scan Filters doc for the usage.

Hi Amanda,

Thank you for your reply.

I I didn't explain well, the NRF_BLE_SCAN_EVT_FILTER_MATCH event is already generated.
My problem is to obtain, during this event, the manufacturer data from the advertisement report or scan response.

p_scan_evt->params.filter_match.p_adv_report->data.p_data does not contain the manufacturer data.

Thanks,

Victor

Hi, 

Guess the manufacturer data might be in the scan response package. This post and this post might help.

Hi,

The scan response packet is empty, whereas it is visible with nRFConnect.

The posts you provided use ble_evt_handler function while I use scan_evt_handler.

Because I don't know how to filter with ble_evt_handler and BLE_GAP_EVT_ADV_REPORT.

Thanks,

Victor

Hi, 

What do you get after printing out p_data?

Could you provide the sniff log? That can help check the data in the advertisement report and scan response.
